Operating instructions
Selecting the temperature scale
Readings are displayed in either degrees Celsius (°C), degrees
Fahrenheit (°F).When the thermometer is turned on, it is set to the
temperature scale that was in use when the thermometer was last
turned off. To change the temperature scale, press the "°C" or "°F" key.
Single-thermocouple temperature measurement
The thermometer displays the temperature of the thermocouple that is
connected to the selected input. Press the "T2" key to display the
temperature of the thermocouple connected to the T2 input. Press the
"T1" key to display the temperature of the thermocouple connected to
the T1 input. The input selection cursor indicates which input is
selected.
Differential temperature measurement
Differential temperature measurement is selected by pressing the
"T1-T2" key. This causes the thermometer to display the temperature
difference between the two thermocouples (the temperature of
thermocouple T1 minus the temperature of thermocouple T2). The
selection is indicated by the input selection cursor.
Selecting the display resolution
The thermometer allows two choices of resolution:
High resolution: 0.1°C or 0.1°F
Low resolution: 1°C or 1°F
Overload display(1)
The digital display will indicate 1 when the input exceeds the
measurement range selected.
If measuring above 199.9º, change the resolution to 1º. Be certain to
seat the thermocouple connector properly and that the leads are not
broken.
